Audio Mixer Devices

You can use the Audio Mixer device to adjust the volume for groups of sounds. This gives you dynamic and automatic control of a game’s volume mix, much like a professional mixing console would.

With the Audio Mixer, you can adjust the volume level of sounds that are already in Fortnite (such as weapons, character footsteps, and vehicles). If you work on your island as a project in Unreal Editor for Fortnite (UEFN), you can create custom sound waves and sound cues that can be controlled with the Audio Mixer as well. See Audio Mixer Device page in the UEFN documentation for more information about using the device in UEFN.

To find the Audio Mixer device, see Using Devices.

Control Bus

In UEFN, the control bus is a way to control certain parameters for one or more sounds. There are several control buses set up to control the volume of the sounds that occur in Fortnite by default. If you don't have a control bus mix set up, or you aren't using UEFN to work on your island, you can choose a default control bus using the Bus option in the Audio Mixer device options. The following table lists the default control buses available.
